Oracle tidsstempel, maks. og minimale værdier

Du kan altid bare prøve det:

SQL> select to_timestamp( '9999-12-31 23:59:59', 'yyyy-mm-dd hh24:mi:ss' ) from dual;

TO_TIMESTAMP('9999-12-3123:59:59','YYYY-MM-DDHH24:MI:SS')
---------------------------------------------------------------------------
31-DEC-99 11.59.59.000000000 PM

og:

SQL> select to_timestamp( '9999-12-31 23:59:59', 'yyyy-mm-dd hh24:mi:ss' )+1 from dual;
select to_timestamp( '9999-12-31 23:59:59', 'yyyy-mm-dd hh24:mi:ss' )+1 from dual
                                                                     *
